3. Fold the dust bag over the edge of the waste material container all round.
▶
Be sure to create an overlap of approx. 5 cm for optimum sealing.
4. Position the suction head on the waste material container.
5. Connect the suction hose.
Fitting a fabric dust bag
1. Remove the suction head from the waste material container.
2. Insert the dust bag into the waste material container.
3. Insert the adapter into the holder provided for the purpose.
4. Make sure that the adapter engages correctly and that the dust bag does not project past the edge of the waste material container.
5. Position the suction head on the waste material container.
6. Connect the suction hose.
Connecting/disconnecting the suction hose
1. To connect, push the suction hose into the intake fitting.
2. To disconnect, twist the suction hose back and forth and pull it out of the intake fitting.
Setting the hose diameter
1. For vacuuming up dry, non-flammable dust which has an exposure limit value, or when vacuuming up wood shavings, adjust the hose
diameter setting switch to the correct diameter setting for the suction hose used.
2. Change the setting for the hose diameter, and consequently the threshold for the acoustic warning, by repeatedly pressing the
Operation
CAUTION
Risk of injury presented by the appliance running away out of control. The vacuum cleaner may run away out of control if the wheel brakes
are not engaged.
▶
Engage the wheel brakes so that the vacuum cleaner stands securely.
WARNING
Risk of injury. Damage to the filter system may allow harmful dust (health hazard) to escape.
▶
In an emergency (e.g. filter ruptured), switch the vacuum cleaner off, disconnect the vacuum cleaner from all power sources (remove battery
or unplug supply cord) and have the vacuum cleaner checked by a trained and qualified person before further use.
DANGER
Risk of exothermic reactions! When dealing with metal dusts such as magnesium or aluminum for example, severe exothermic reactions (e.g.
fire, explosions) can occur. Consequently, there is an increased risk of injury due to burns and explosions.
▶
Familiarize yourself with the properties of the dusts and before starting work, acquaint yourself thoroughly with the necessary safety
measures.
▶
Be aware of the dangers that can result from a combination of materials. These include, among other things, chemical reactions between
metal dusts or between metal dusts and water.
Switching the vacuum cleaner on or off
Switching on vacuum cleaner and selecting operating mode
1. Turn the operating mode rotary switch to one of the following functions:
▶
ON: The vacuum cleaner runs in the normal operating mode
▶
AUTO : The vacuum cleaner can be controlled automatically via a connected system product or via a Bluetooth connection.
Follow the instructions on safety and use in the operating instructions of the system product or the accessory.
Switching off vacuum cleaner
2. Turn the operating mode rotary switch to the OFF position.
Bump-cleaning main filter
You can bump-clean the filter only when the vacuum cleaner is switched on.
1. Close off the end of the hose.
▶
This maximizes bump-cleaning power.
2. Wait until maximum vacuum has built up.
3. Press the
operating button.
Vacuuming up dry dust
CAUTION
Risk of injury by dusts that are hazardous to health! Hazardous material that has been vacuumed up can escape if a main filter is not used.
▶
Use the vacuum cleaner only with a main filter inserted.
Before vacuuming up dry dust, especially dust from mineral materials, always check to ensure that the correct dust bag is fitted in the
container. The material vacuumed up by the vacuum cleaner can then be disposed of cleanly and easily.
